Modelling of water regime in karst / Modeliranje vodnih režima u karstu
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
Underground flow regime in karst areas completely differs from flow in intergranular aquifers. Hydraulically, this flow can be better described as a system of reservoirs and pipes with flow under pressure and with free ...
Contracting-expanding chute numerical modelling / Numeričko modeliranje brzotoka pri promeni pravca zida kanala
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2005)
Two-dimensional (2D) open-channel flow models for contracting and expanding chutes are developed. TVD McCormack and TVD MUSCL method have been used to facilitate an easy-to-use code. The performances of the numerical models ...
Određivanje garantovanih ekoloških protoka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, 2000)
Jedna od ključnih projektnih odluka pri planiranju akumulacija je koliki garantovani ekološki protok odabrati, kao obavezno ispuštanje iz akumulacije. Na bazi analize metoda koje se koriste u svetu za određivanje tog ...
Model generator of water consumption and hydraulic simulation model in water supplying network / Model generator potreba za vodom i hidraulički simulacioni model vodovodne mreže
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Research and development of random sampling procedures in creating model generator of water demand time patterns is shown. Also a composite package combining stochastic nature of water demand and hydrodynamic simulation ...
Polynomial interpolation problem for skew polynomials
(Univerzitet u Beogradu - Elektrotehnički fakultet, Beograd i Akademska misao, Beograd, 2007)
Let R = K[x;δ] be a skew polynomial ring over a division ring K. We introduce the notion of derivatives of skew polynomial at scalars. An analogous definition of derivatives of commutative polynomials from K[x] as a function ...
Modeling of properties of fiber reinforced cement composites / Modeliranje svojstava mikroarmiranih cementnih kompozita
(Univerzitet u Nišu, Niš, 2008)
This paper presents the results of authors' laboratory testing of the influence of steel fibers as fiber reinforcement on the change of properties of cement composite mortar and concrete type materials. Mixtures adopted - ...
Testing of properties and application examples of CFRP strips for strengthening of concrete structures / Ispitivanje svojstava i primeri primene karbonskih traka za ojačanje betonskih konstrukcija
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2008)
The results of authors' own laboratory testing of two CFRP strip types - Sika CarboDur Plates and SikaWrap fabrics, as well as the corresponding Sikadur epoxy adhesive used for bonding and/or impregnation of CFRP strips, ...
Experimental testing of certain thermo-physical and mechanical properties of EPS concrete / Eksperimentalna ispitivanja određenih termo-fizičkih i mehaničkih svojstava EPS betona
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
In this paper the experimental results obtained during testing of certain important properties of EPS concrete as a type of lightweight composite material - regarding Civil engineering physics are presented. Most of the ...
Possible application of self-compacting concrete / Mogućnost primene samozbijajućeg betona
(Univerzitet u Novom Sadu - Građevinski fakultet, Subotica, 2007)
The results of laboratory testing of self-compacting concrete (SCC) made with a new-generation superplasticizer are presented in this paper. The testing was performed both in normal curing conditions (specimens cured in ...
Coefficient characterization for certain classes of univalent functions
(Bulletin of the Belgian Mathematical Society - Simon Stevin, 2009)
Necessary and sufficient coefficient conditions are established for certain
classes of analytic functions to be univalent in the unit disk. In addition,
characterizations and convolution results are established for these ...
